Compilation Method and Compiler for Heterogeneous System

Abstract

The invention provides a compilation method and a compiler for a heterogeneous system. The compilation method for the heterogeneous system includes that system service statements are recognized, calculation statements are separated from the system service statements, and then the system service statements are identified; format parsing is carried out to the system service statements, and then system service information data is collected; a first statement is generated in a sub core program, the system service information data is packed and sent to a main core end input (I) / output (O) buffer, and then a service request is sent to a main core end; a second statement is generated in a main core program and includes a sub core computational load service program and a system service program corresponding to the service request; and a third statement is generated in the main core program, polling processing is carried out to the system service program based on identification, and then the system service program is processed based on the data in the main core end I / O buffer. By means of the compilation method and the compiler for the heterogeneous system, user-level isomorphic perspective programming is achieved in the heterogeneous system.

Description

Technical field [0001] The invention relates to a compilation method and a compiler, and particularly relates to a compilation method and a compiler of a heterogeneous system. Background technique [0002] A heterogeneous system is a computing system composed of processors with different functions and performances connected through a certain interconnection structure. A heterogeneous system is generally composed of a general-purpose microprocessor and a dedicated accelerated processor. In a heterogeneous system, it is necessary to use The general-purpose microprocessor controls and manages the operation of the accelerator to form a master-slave architecture. The general-purpose microprocessor is the master core and the accelerator is the slave core. According to the integration mode of master core and slave core, it can be divided into chip level and device level. The chip-level heterogeneous system integrates different types of computing components for different instructions wi...

Problems solved by technology

[0004] However, in the prior art, the programming methods on the heterogeneous system all adopt the accelerated programming mode of the heterogeneous perspective, which is described as the master core code running on the general-purpose microprocessor and the slave core code running on the special accelerator. Agile programming of application software brings difficulties. Programmers often need to understand complex hardware details in order to effectively develop the computing potential of accelerators, which poses a great challenge to programmers

And a large number of existing applications cannot be quickly and effectively transplanted to run on heterogeneous systems
